Spectral criteria for generalization in unsupervised Hebbian nets
Elena Agliari, Paulo Duarte Mourão, Alberto Fachechi +1
We consider an unsupervised Hebbian network where the pairwise interactions among neurons are built on noisy realizations of hidden ground-truth vectors. Unlike classical Hopfield…

The importance of being empty: a spectral approach to Hopfield neural networks with diluted examples
Elena Agliari, Alberto Fachechi, Domenico Luongo
We consider Hopfield networks, where neurons interact pair-wise by Hebbian couplings built over . a set of definite patterns (ground truths), . a sample of labeled examples…

Multi-channel pattern reconstruction through -directional associative memories
Elena Agliari, Andrea Alessandrelli, Paulo Duarte Mourao +1
We consider -directional associative memories, composed of Hopfield networks, displaying imitative Hebbian intra-network interactions and anti-imitative Hebbian inter-networ…
